Seabuckthorn oil is 100% effective for stomach ulcers. Make sure it is a real one, not processed in a capsule form. I know a person who was scheduled for a surgery to repair an ulcer and by pure chance was given this oil and in 3 days she had to cancel the surgery. Other comments I received-I am a god sent savior. A person in the UK was so impressed that she planted it in her yard. Works for colitis as well.
